  1. 1. Coping with decisions on deviations in complex product development projects

    Författare :Joakim Eriksson; Björn Fagerström; Yvonne Eriksson; Niels Henrik Mortensen; Mälardalens högskola; []
    Nyckelord :Innovation and Design; innovation och design;

    Sammanfattning : A strong need for resource efficiency within manufacturing companies have been driven extensively through pro-active planning and methods which have naturally resulted in an increased amount of strong couplings between product development projects, their activities, and resources. These strong couplings mean a high level of complexity where deviations are likely to occur on a regular basis which can spread quickly and have far reaching consequences. LÄS MER

  2. 2. Dynamic Decades: A micro perspective on late nineteenth century Sweden

    Författare :Björn Eriksson; Centrum för ekonomisk demografi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; microeconomic data; industrialization; female employment; competition; firm survival; social mobility; migration;

    Sammanfattning : This dissertation examines various aspects of mobility during the closing decades of the nineteenth century in Sweden. In terms of the pace and magnitude of the changes taking place during this industrial breakthrough, no other period in Swedish history compares. LÄS MER

  3. 3. Effects and nature on buffer ion enrichment in electric field assisted liquid chromatography

    Författare :Björn Eriksson; []
    Nyckelord :;

    Sammanfattning : The aim of this study has been to investigate the properties and limitations of the separation technique electric field assisted capillary liquid chromatography (EF-LC). The electric current in the EF-LC has shown to be a limiting factor and has been the focus of the study. LÄS MER

  4. 4. Electrochemical evaluation of new materials in polymer electrolyte fuel cells

    Författare :Björn Eriksson; Carina Lagergren; Göran Lindbergh; Rakel Lindström; Piotr Zelenay; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Fuel cell; Pt-REM; Alloy catalyst; Multi walled carbon nanotubes; Bipolar plates; Water transport; Bränslecell; Pt-REM; Legerad katalysator; Flerväggade kolnanorör; Bipolära plattor; Vattentransport; Chemical Engineering; Kemiteknik;

    Sammanfattning : Polymer electrolyte fuel cells (PEFC) convert the chemical energy in hydrogen to electrical energy and heat, with the only exhaust being water. Fuel cells are considered key in achieving a sustainable energy sector. The main obstacles to wide scale commercialization are cost and durability. LÄS MER

  5. 5. Heart failure with preserved ejection fraction in primary care

    Författare :Björn Eriksson; Karolinska Institutet; Karolinska Institutet; []

    Sammanfattning : Background Heart failure with preserved ejection fraction (HFpEF) is a condition associated with low quality of life, high morbidity and mortality. It constitutes a diagnostic challenge and there is little evidence of effective treatments. LÄS MER
